DU PLEX STEAWl-EJECTOR.V

SPECIFICATION forming part of LettersPatent `1\T o. 676,239, dated June 11, 1901.

Application filed November 13, 1900. Serial No. 36,382. (No ruodeL) Be tknown that I, WILLIAM D. LABADIE, a citizen of the United States, residing at South Bend, in thecounty of St. Joseph and State of Indiana, have invented certain new and useful Improvements in Duplex Steam-Ejectors; and I do hereby declare the following to be afull, clear, and exact description of the invention, Such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in duplex steam-ejectors; and its object is to use in different branches of the same pipe separate ejectors, so as to enable a larger amount of water to be raised than has heretofore been done with the sameamount of steam.

My invention consists in a pipe through which the Water is raised and which is provided with several branches combined with a separate ejector for each one of the branches 'and a steam-pipe which feeds all of the ejectors, as will be more fully described hereinafter.

The accompanying drawing represents a vertical section of an ejector which embodies my invention.

A represents the suction -pipe, through which the Water rises to the ejeetors, and placed upon the top of this pipe is the easting B, having two or more curved branches,

which branches diverge from the same pointV near the lower end of the casting and unite at its top. These branches are preferably made curved, as here shown, so as to present less obstruction to the free flow of the water,

and in each branch is placed a horizontal paryond the plugs Gare the conical pipes I, which have their upper ends to project into the lower ends vof the ejector-pipes D any desired 5o distancein the usual well-known manner. Connected to each of the plugs or couplings G are branches J, extending outwardly from the lower end of the steam-pipe O,and through which steam-pipe and its branches J steam is forced through the ejectors for the purpose of raising water in the'usual manner. I have discovered that -by connecting more than one branch to the main suction-pipe and using a separate ejector in 'each branch a larger 6o amount of water c anbe raised with the same amount of steam than has heretofore been possible by the use of a single pipe. Owing to the ejector devices placed in the pipes, but a limited amount of water can be forced through thedevices, andvhence a' powerful pressure of steam is necessary to raise any thing like a considerable volume of water.

`By having a number of branches connected with the suction-pipe and placing an ejector 7o in each one the amount of water that can be raised by the same pressure of the steam is Very greatly augmented and a great saving in expense is made.

Having thus described my invention, I claim- In an ejector, the suction-pipe, a casting B secured to its upper end and having two or more curved branches extending therethrough, each of the branches being provided 8o with a partition, and a shoulder, combined with the ejector pipes D, which project through the partition, the steam-nozzles G, plugs or couplings for closing the perforations through the shoulders in the casting, the 8 5 branch pipes J, and the steam-pipe O, from `which all of the ejectors are fed simultaneously, substantially'as specified.

In testimony whereof I aiiix my signature in presence of two witnesses.
